Handgrip

Abstract

Provided is a handgrip including first and second operating arms that are spaced apart from each other; first and second link arms that are sequentially and obliquely disposed between the first and second operating arms, and of which both ends are rotatably connected to the operating arms, respectively, through rotating shafts; and a spring member that is installed to provide an elastic force biasing the first and second operating arms apart from each other.

The invention claimed is: 
     
       1. A handgrip comprising:
 first and second operating arms that are spaced apart from each other; 
 first and second link arms that are sequentially and obliquely disposed between the first and second operating arms, and of which both ends are rotatably connected to the operating arms, respectively, through rotating shafts; 
 a spring member that is installed to provide an elastic force biasing the first and second operating arms apart from each other; 
 a body portion that is provided at the top of the first operating arm, wherein the body portion includes:
 a sidewall which supports one end of the spring member; 
 a guide member which passes through the sidewall of the body portion so as to extend in the longitudinal direction of the body portion; 
 a spring support portion which is fixed to an end of the guide member at the first operating arm and supports the other end of the spring member such that the spring member is interposed between the sidewall and the spring support portion; and 
 a spring operating portion which is installed in a space positioned at a side surface of the sidewall facing the installation position of the spring member, and coupled to the guide member so as to be moved together with the spring support portion, and an upper end portion of the first link arm extends above a rotating shaft as a connection portion between the first operating arm and the first link arm, and comes in contact with a side surface of the spring operating portion at the first operating arm, thereby pressing the spring operating portion. 
 
 
     
     
       2. The handgrip according to  claim 1 , wherein the spring operating portion is formed of a nut-shaped member fixed to the guide member through a screw coupling method, and the position thereof is adjusted while the spring operating portion is moved along the guide member. 
     
     
       3. The handgrip according to  claim 1 , wherein the guide member extends through a through-hole formed at the end of the body portion to the outside, an elastic force adjusting screw is coupled to an end of the guide member extending through the through-hole so as to move along the guide member, the position of the elastic force adjusting screw is supported by the body portion in a state in which the two operating arms are released, and a distance between the spring support portion and the sidewall is adjusted by the elastic force adjusting screw. 
     
     
       4. The handgrip according to  claim 3 , wherein a support roller for supporting the guide member is installed at the end of the body portion so as to be disposed above the through-hole. 
     
     
       5. The handgrip according to  claim 3 , wherein the elastic force adjusting screw has an opening passing through an outer surface thereof, through which the position of the guide member is checked. 
     
     
       6. The handgrip according to  claim 2 , wherein the guide member extends through a through-hole formed at the end of the body portion to the outside, an elastic force adjusting screw is coupled to an end of the guide member extending through the through-hole so as to move along the guide member, the position of the elastic force adjusting screw is supported by the body portion in a state in which the two operating arms are released, and a distance between the spring support portion and the sidewall is adjusted by the elastic force adjusting screw. 
     
     
       7. The handgrip according to  claim 6 , wherein a support roller for supporting the guide member is installed at the end of the body portion so as to be disposed above the through-hole. 
     
     
       8. The handgrip according to  claim 6 , wherein the elastic force adjusting screw has an opening passing through an outer surface thereof, through which the position of the guide member is checked.
